Troubleshooting & FAQ

How do I confirm this kit fits my specific engine?

The most reliable method is to match your engine's model, year, and serial number against our compatibility table. This kit is for V6 Mercury/Mariner engines using WMH series carburetors. The 'Notes' column in the compatibility chart contains specific serial number ranges and carburetor models (e.g., WMH-8, WMH-12A) that are critical for confirming fitment.

What are the signs my carburetor needs a rebuild?

Common symptoms include hard starting, rough idling, stalling,bogging down on acceleration, black smoke from exhaust, and visible fuel leaks. These issues often arise from old, cracked, or shrunken gaskets and diaphragms that cause air or fuel leaks.

What is a WMH series carburetor?

WMH is a carburetor model manufactured by Mercury Marine. You can typically find the model number stamped directly on the carburetor body. Verifying this model is a key step in ensuring you purchase the correct rebuild kit.

Do I need special tools for this job?

You will need standard mechanic's tools, such as socket wrenches, screwdrivers, and pliers. A dedicated carburetor cleaner spray and a clean workspace are highly recommended. A torque wrench can also be helpful for reassembly to avoid over-tightening screws.

Is everything I need to rebuild one carburetor included?

This kit includes all the necessary gaskets and diaphragms to rebuild one WMH series carburetor. If your V6 engine has multiple carburetors, you will need to purchase one kit per carburetor for a complete service.

Do I need to adjust the carburetor after rebuilding?

Yes, it is common to need minor adjustments to the idle speed and air/fuel mixture screws after a rebuild to ensure the engine runs smoothly. Refer to your engine's service manual for the correct procedure and baseline settings.
